Fifteen-inch guns offer a strong battleship balance

What gun size offers the best balance for a battleship?

He would probably choose a 15-inch gun because it balances hitting power, ammunition carried, hull stress, and practical advantage better than always chasing a larger caliber.

The 16-inch gun has obvious appeal, but the extra caliber must justify what it gains over a 15-inch weapon. Larger guns add stress and reduce what a ship can carry or balance elsewhere. The personal choice is therefore a 15-inch gun. It offers a strong compromise among power, practicality, ammunition, and logistics.
